Laser teeth whitening combines in-office application of a peroxide bleaching solution with laser energy that “activates” the whitening process and speeds it up significantly. While whitening treatments reduce stains a great deal, they do not permanently keep teeth at a lighter shade. To ensure that teeth remain as white as possible, avoid over-consumption of beverages that cause stains, including red wine, coffee, and tea. A straw can help those who do drink these beverages regularly to avoid stains on the highly visible front teeth.

Another strategy involves rinsing or brushing the teeth directly after consuming tooth-staining beverages. Use of whitening toothpaste twice a week and proper oral hygiene that removes plaque are also important factors in ensuring that staining is kept to a minimum. Many patients who have undergone in-office laser whitening procedures also benefit from touch-up treatments every six to 12 months.
